"She called me and, yeah, she was attacked outside," Cowell said on Ryan Seacrest's radio show on Thursday. "Literally, a frenzied attack. Nearly strangled. A hundred percent serious."

Cowell said that he's never met Thibodeaux, adding, "Naturally, I assumed it was somebody who was jealous. I don't know, it was just some crazy girl. She's locked up."

As for Seymour, Cowell said that it was quite a shocking incident for her. "It was bad. I really, really felt sorry for her," he said. "You know what? I was there for her, Ryan. That's the important thing."

Thibodeaux claimed to have once been a security guard at "Idol" but had purchased a ticket for the show on Tuesday. Though she tried to flee on foot, the incident was allegedly witnessed by police and she was arrested and charged with two misdemeanor counts of battery and assault, according to TMZ. She faces a maximum sentence of 18 months in jail and $12,000 in fines if convicted on both charges.

Thibodeaux said she wanted to talk to Cowell about how he playfully choked Abdul during an earlier show. "I wasn't cool with Simon Cowell choking Paula Abdul on the show last week and with her crying out 'help' as he did so," Thibodeaux said from jail. "Nobody said anything about that, so I wanted to confront him about it, because that is not appropriate behavior, is it?"
